MiniBoard Standard

Our MiniBoard Service is our least expensive PCB option. These are the same high quality PCBs as our other manufacturing services, but with a fixed size and quantity. By standardizing the size and number, we can offer these boards at a very low price.

Cutoff Time for all services is 2 PM Eastern Time. We only manufacture orders placed via our ExpressPCB Software.

Description

Standard MiniBoards are two layer boards with plated through holes. They do not include the solder mask or silkscreen layers which are primarily cosmetic. Electrically, these boards are first rate with bright shiny traces and pads. Because they do not have green solder masks, they are the yellowish color of the industry standard FR-4 laminate.

Standard MiniBoards are 2 layer PCBs without the solder mask or silkscreen layers.

For a fixed price of $51, you will receive 3 identical boards.

The board’s size must be 3.8 x 2.5 inches.

Orders submitted Monday through Friday by 2:00pm ET are shipped the next business day.

Multiple circuits can be pasted together on a single board, but we do not cut them apart. The perimeter of a board cannot include long slots as they can cause manufacturing problems. We are not responsible for any defects that are a result of routing multiple circuits on a single board.

Our 2 layer laminate is .059" FR-4 epoxy glass which includes .0007" copper on each side (industry standard 1/2 ounce copper base). We plate an additional .001" copper on the surface after drilling and imaging, resulting in a copper thickness on the surface of ~0.0017″.

These sizes are the finished hole diameters after plating. The 0.014″ hole may be filled with solder and can only be used as via. The tolerance for the 0.020″ hole is +0.003 / -0.005. The tolerance for the other hole sizes are +/- 0.004″.

Hole Location Tolerance

Our hole location tolerance is +/- 0.005”. As such, the tolerance between two holes would be +/- 0.010”.

Minimum Hole Distance

A minimum of 0.021″ space must remain between adjacent holes. For example, the center-to-center distance between two pads with 0.020″ holes must be 0.041″ or greater.

Internal Slots and Cutouts

None

Perimeter Slots

No Perimeter Slots

Perimeter Routing

The edges of the board are cut with an accuracy of +/- 0.015″. A minimum of 0.020″ blank space is recommended between the perimeter and all features on the board. Traces placed closer than 0.015″ to the board’s edge may be routed off.

Temperature

The maximum operating temperature is 125 degrees C.
